What does an illuminated coolant temperature light mean for my GMC?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

Can an antifreeze leak wait?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

When should my GMC Terrain radiator be cleaned?

To keep your GMC Terrain radiator running well, it’s wise to get it cleaned out a few times a year.

What can cause my Terrain to overheat?

Your GMC Terrain engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

Why does the radiator in my Terrain sound like it’s rumbling or boiling?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your Terrain. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

There’s rust in my Terrain radiator. Should I be worried?

Yes. Rust in your GMC Terrain radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.

When Does My 2021 GMC Terrain Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your GMC Terrain radiator serviced. Nonetheless, it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Regular, proactive service on the radiator in your 2021 GMC Terrain is essential for long-term engine health. In fact, GMC recommends replacing coolant/antifreeze at specific intervals, but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

GMC Terrain Coolant Fluid Exchange

What does radiator repair include? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your GMC Terrain. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

Issues with your radiator often coincide with a malfunctioning water pump. The water pump is one part on your 2021 GMC Terrain engine that you'll want to have repaired or replaced as soon as you discover a problem with it. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to help make sure everything is in working order. From the heater core to the radiator cap, your 2021 GMC Terrain is in good hands at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.
